Tilastopaja in the results of the race put QUESTIONABLE COURSE LENGTH after each Marathoners Result.
They have NOT (Yet) put the Results in the ALL Time List's ( I am not sure if they will with the adjusted times), Kind of like When Bill Rodgers ran 2:08.23 in Sado Island, Japan (MIGHT have been a World Record at the time as I THINK Derrick Clayton's 2:08.33 was the World Record at that time) but it was found to be 100-200 meters short, So if they had measured it right it WOULD NOT be a World Record, but It Would have been a CAREER PERSONAL BEST.
Oh well I am sure those 2 will run faster than that in a less humid race, next year maybe 2:03's, now that Kipchoge ran 2:01.39 more people will run 2:02-2:03 more frequently.
